}Reject a pending agent action (and terminate its run)
Reject a require_approval action raised by one of your headless runs.
The deferred tool is NOT executed; a denial note is appended to the run’s
conversation and the owning run is terminated with status: rejected.
Requires the agents:approve scope and ownership of the owning run.
Consequential — writes an audit entry.
Two gates, not one. Owning the run is what lets you see the
approval — it does not make you a valid approver. Because your own run
raised the action, every decision here is by definition a
self-approval, so the credential’s bound user ALSO needs the
ai.approve_actions RBAC permission (held by a facility admin scoped to
the approval’s facility, or an internal operator). A credential with
agents:approve whose user lacks ai.approve_actions gets 403
SELF_APPROVAL_FORBIDDEN.

}Authorizations
API key or personal access token (NEX-1042). Send as
Authorization: Bearer <token>. Token format:
nex_live_…— live API key (server-to-server)nex_test_…— sandbox API keynex_pat_…— personal access token (acts as the issuing user)
Authorization is decided by the key's scopes array, not the
owning user's RBAC role. See POST /api/api-keys to mint a key.
Headers
Pin the request to a dated API version (e.g. 2026-05-10). Applied by app-level middleware to every /api route (server/routes/index.ts → apiVersionMiddleware), which echoes the resolved value back in the NexSpace-Version response header. Omit to get the latest version. Discover the catalog at GET /.well-known/api-versions.
^\d{4}-\d{2}-\d{2}$Replay guard for write requests. Applied by app-level middleware to every /api route (server/routes/index.ts → idempotencyMiddleware), which only acts on POST/PUT/PATCH — GET, DELETE and OPTIONS ignore the header. Re-sending the same key with an identical body within 24 hours replays the original response; the same key with a different body returns 409.
